LEAP Bridge V8i

New Features in CONSPAN v.9.0.0

• Deck slab design using the approximate/strip method as specified in LRFD Art. 4.6.2.
  
  
• Updated to the 2009 LRFD specification. The fatigue limit state is automatically considered in the design, with a 1.5 load factor and a check for compression stresses under ½(DL+PS) + 1.5(fatigue live load).
  
  
• An automatic strand generation option has been added when user selects the pull percentage/CG of strands input method as compared to the strand by strand approach.
  
  
• Updated to the 2009 Florida DOT Structure Design Guidelines (SDG).
  
  
• CONSPAN has been updated to handle deck bulb tees sections without topping, computing more accurate live load distribution factors as per the provisions of the LRFD specifications.
  
  
• The rating dialogs have been updated to allow for selection of up to 50 trucks for load rating.
  
  
• A new summary rating report has been added to allow the user to obtain rating results for one span, or for the bridge as a whole.
  
  
• A new load rating vehicle, Notional Rating Vehicle, has been added to the library as per the Manual for Bridge Evaluation, 2008.
  
  
• A new option to not compute concrete stresses at the top of topping has been added. This option is now the default option.
  
  
• A new option to ‘Retain Beam Level Changes' has been added at the program level under Preferences, so changes in the beam level are not overwritten based on settings in the project parameters.
  
  
• The beam dialog has been updated to show a summary of the beam/location stresses and moment, as a cursor is moved along the bridge amongst predefined locations.
  
  
• A new option to define materials at the beam level (under data modification) has been added. Previous versions required all spans and beams to have the same material properties.
  
  
• A new option to neglect elastic shortening losses under LRFD prestress losses has been added.
  
  
• The automatic strand pattern generation algorithms were fine-tuned to generate strands in more cases.
  
  
• A diaphragm load wizard has been introduced in this version to facilitate quick and easy input of diaphragm loads.
  
  
• A new ‘Copy to' button has been added under diaphragm loads input.
  
  
• A new field named ‘Sacrificial deck thickness' has been added on the Geometry tab to allow the user to model the non-structural deck thickness. The self weight of this sacrificial deck thickness is computed internally by CONSPAN.
  
  
• 2D graphics have been improved to show beam numbering in cross-section and plan views. Also a new button called ‘View Options' has been added in such 2D drawings to help the user benefit from advanced functionality available. In addition, 2D drawings show a schematic representation of the curbs on the bridge.
  
  
• 3D views now show more realistic 3D shapes as defined by user drawn sections in the beam library.
  
  
• Reports enhanced to now include fields for checked by, checked date, option to print time stamp on reports, set the font on enhanced reports and re-organized headers.
  
  
• CONSPAN is now available under Bentley Educational License.
